Proteomic profiling of bacterial host adaptation : Racing the Red Queen

Despite the discovery of antibiotics almost a century ago, infectious diseases continue to be a substantial cause of human mortality and morbidity worldwide, especially in developing countries. The adverse affects of infectious diseases are thought to increase over the coming years as the widespread misuse of antibiotic leads to the emergence of strains for which current therapies are ineffective.

Darriwilian (Middle Ordovician) worms of southern Sweden

The record of scolecodonts (polychaete jaws) from the Ordovician of Sweden is very poor. In this paper, we document a Darriwilian (Middle Ordovician) assemblage recovered from palynological samples from the “orthoceratite limestone” (Lanna and Holen limestones) of Mount Kinnekulle, Västergötland, southern Sweden. The collection of diminutive specimens forms an assemblage taxonomically composed mai

Projekt Bygginnovationen: Betongreparation

Artikeln är en sammanfattning av delprojektet Betongreparation inom det större projektet Bygginnovationen som är ett nationellt flerårigt forsknings-och utvecklingsprogram finansierat av Vinnova och svensk byggindustri. I artikeln görs en beskrivning av olika betongskador. Åldersfördelningen hos svenska konstruktioner beskrivs. Principer för val av reparationsmetod och reparationsmaterial diskuter

Sprickbildning i puts på isolering

Vid byggnadsmaterial, Lunds tekniska högskola, har problem med sprickbildning i puts på isolering studerats under ett antal år. Projektet startade i större skala 1999 med generella brottmekaniska analyser, laboratoriemätningar av brukets egenskaper och "fullskaleförsök" på provväggar i laboratorium. Resultaten från de första årens studier redovisades översiktligt i Bygg & teknik 8/02. Bland an

Sprickbildning i puts på isolering

Sprickbildning i puts på isolering har inträffat i ökande omfattning på senare tid. 1997 togs problemställningen upp vid Byggnadsmaterial, Lunds Tekniska Högskola. Genom brottmekansika beräkningar, renodlade laboratorieförsök samt studier på provväggar och analys av skadefall i praktiken har olika inverkande faktorer klarlagts. I denna artikel sammanfattas hittills framkomna resultat och hypoteser

Baseline trabecular bone and its relation to incident radiographic knee osteoarthritis and increase in joint space narrowing score : directional fractal signature analysis in the MOST study

Purpose To explore the association of baseline trabecular bone structure with incident tibiofemoral (TF) osteoarthritis (OA) and with increase in joint space narrowing (JSN) score. Methods The Multicenter Osteoarthritis Study (MOST) includes subjects with or at risk for knee OA. Knee radiographs were scored for Kellgren–Lawrence (KL) grade and JSN at baseline, 30, 60 and 84 months. Knees (KL ≤ 1)

Direct Conversion of Fibroblasts to Megakaryocyte Progenitors

Current sources of platelets for transfusion are insufficient and associated with risk of alloimmunization and blood-borne infection. These limitations could be addressed by the generation of autologous megakaryocytes (MKs) derived in vitro from somatic cells with the ability to engraft and differentiate in vivo. Here, we show that overexpression of a defined set of six transcription factors effic

A 15-Gb/s wireless on-off keying link

Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates,
